Leave the weight on the bar so that the next person to use it has to take it all off and realize how strong you really are. Ignore your spotter. If he starts to say something about depth, yell over top of him, "what kind of LOUSY spot was that?" To anything he says after that, just laugh him off immediately. Exit the gym by the same route you took to get in. Do not remove your belt and remember those barrels.
